I have replaced mine with a battery from Batteries Plus...They generally have them on the shelf --- about $130.00 I always take the old one in just to make sure.
Group 34 Optima Yellow Top was my choice for my 2015.
Lithium is a another choice but also more$.
You will have suggestions for all types and mfgs of batteries, pick your price point and go for it.
You do not even need the larger battery unless you are running a bunch of lights or a big stero system

Thanks for confirming my thoughts.

I installed the larger battery to get rid of the lead acid battery because of the corrison

I am considering going to a sealed, maintenance free, battery, for the reason you describe, but my experience with these in the past is that they have a shorter life span?

34 Yellow Top for me as well and I'm happy with it. It likes to be charged at higher rate so got a higher output alternator, but before that the trickle charger would top it off just fine too. System sounded a lot better with the extra power!
Interstate MTX-47/H5 for me.
The stock 2015 - 16.5 battery is a Group 26. A Group 34 will also fit and generally offers more capacity, but may cause some clearance issues with certain thru-transmission tunnel aftermarket exhausts unless properly positioned to clear the exhaust.
If you live near a Rural King store, they place a Group 34 AGM battery on sale several times per year, sometimes under $100. Pep Boys sells a Bosch AGM battery that appears to be the same battery, but their sale price is usually closer to $140-150.
If you have a 2016.5 or newer Slingshot with the smaller motorcycle battery, the major Slingshot parts vendors offer replacement battery trays that will hold a larger battery.
The Gen 2 2020+ Slingshot relocated the battery from behind the driver's seat to the engine compartment, but still uses the smaller motorcycle battery introduced in the latter portion of 2016 model year production.

The group 25 is the same size as the 34 except it is one inch shorter in length, which is what I am running. Also buy the dual post battery. If you are running a rear exhaust just be sure to pull the battery all the way to the battery cover before tighting and installing the cover
I went with a Costco interstate group 34 battery and it's tight! Pushed it as far as I could, but with the welter duals, it was close... So I wrapped the battery with insulation kit and wrapped the exhaust pipe with a heat shield.
All that's left is to pray the battery won't melt and hope for the best!

As I shared in my original post, it appears that the 4014132-P battery from Polaris for the 2015-2016 SlingShots is no longer available?

I just wanted some price info and never even looked at the part number.

Sorry, I was just pointing out that this battery is yet another item that can be added to the ever growing list of parts that is no longer available.

At least Group 26 battries are still available from many retailers. Walmart has a Group 26R for $55. The R means the battery polarities are reversed and new cables or extensions might be needed.

Doing some quick research, it appears that to get the OEM 575 CCA, one is going to need to go to the size 34? Though, in reality, 525 CCA in a size 26 would probably be ample in a stock vehicle?

Yous won’t melt, you don’t drive it enough!

He's the only guy I know who bought a used Slingshot and it has fewer miles on it today than the day he brought it home!
